MITSUBISHI <Dig./Ana. INTERFACE> M62364FP 8-BIT 8-CH MULTIPLYING D-A CONVERTER WITH BUFFER AMPLIFIERS GENERAL DESCRIPTION PIN CONFIGURATION (TOP VIEW) The M62364FP is a CMOS 8-bit, 8-ch D/A converter having a multiplying function and output buffer amplifiers. It has a serial data input and can easily communicate with a microcontroller by the simple three-wiring method (DI, CLK, LD). The output buffer amplifiers operating in AB-class has both sinking and driving capabilities of 1.0mA or more and can operate in a whole supply range from VDD to GND. The IC is suitable for a use in automatic adjustment applications in conjunction with a MCU by utilizing the terminal DO for a cascading connection. FEATURES • Three-wiring serial data transmission • Doubled precision 8-ch D/A converter employing an R-2R with higher-order segment method • 8 buffer amplifiers operating in a whole supply voltage range from VDD to GND • 4-quadrant multiplication M62364FP VIN1 1 VOUT1 2 VOUT2 3 VIN2 4 VDD 5 LD 6 CLK 7 DI 8 VIN3 9 VOUT3 10 VOUT4 11 VIN4 12 24 23 22 21 20 19 18 17 16 15 14 13 VIN8 VOUT8 VOUT7 VIN7 GND RESET VDAref DO VIN6 VOUT6 VOUT5 VIN5 Outline 24P2Q (FP) APPLICATION Digital to analog conversion for consumer and industrial equipment.

Input data of DI are taken into the 12-bit shift register on a rising edge of the clock. 6 LD A low state enables data loading to the 12-bit shift register. During a rising edge of LD, the data will be loaded to the output register. 19 RESET Reset 8-bit latches 2 VOUT1 3 VOUT2 10 VOUT3 11 VOUT4 14 VOUT5 15 VOUT6 22 VOUT7 23 VOUT8 5 VDD Power Supply 20 GND Ground 1 VIN1 4 VIN2 9 VIN3 12 VIN4 13 VIN5 16 VIN6 21 VIN7 24 VIN8 18 VDAref D/A Converter Output with 8-bit resolution D/A Converter Input D-A Converter Reference Voltage Input MITSUBISHI ELECTRIC (2 / 6 ) MITSUBISHI <Dig./Ana.
